We are aware of this issue. This bug is already logged in our bug tracking system. We will try to get this fixed in upcoming release in summer. At this point , the workaround would be to create the layout in the activity and add the MapView from within the activity.

 protected override void OnCreate(Bundle bundle)
{
 base.OnCreate(bundle);
 layout = new LinearLayout(this) { Orientation = Orientation.Vertical };
 new MapView();
 Map = new Map(Basemap.CreateImagery());

 ButtonStart = new Button(this);
 Text = "Start";
 Click += BtnClickAsync;

 AddView(ButtonStart);
 AddView(_mapView);
 layout);
}
